1. A variable length frame exchanging method by a fixed length cell handling exchange which handles fixed length cells each including a first logic channel information, a logic path information and a data section and to which a terminal adapted for a data communication using a variable length frame including a second logic channel information is connected by a transmission line having at least one channel, the method comprising the steps of:

  • disassembling the variable length frame transmitted from said terminal into fixed length cells;

    translating the second logic channel information in the variable length frame into the first logic channel information and the logic path information for the fixed length cells; and

    providing the first logic channel information and the logic path information obtained in said translating step for the fixed length cells obtained in said disassembling step and inputting the fixed length cells with the first logic channel information and the logic path information to said exchange.
